Just be warned! Be very careful when you are alone and face strangers. Police are urging visitors to the city center to be especially vigilant for a new gang operating a slick routine that is aimed at stealing from unwary persons.

They say that the gang usually comprises four members. While the three younger ones, all appearing to be cute and innocent, divert their "mark" (or intended target) with a show of friendliness and fun, the fourth the eldest of this gang of criminals sneaks in from behind the person's back to expertly rifle undetected through their pockets and bags for any valuables being carried.

The adjacent picture taken from CCTV shows the gang in operation. (Click it to enlarge.)
